lins or the like permitting their modification for this purpose.

A still further object of the invention is to provide a device of this character which may be readily and cheaply manufactured,

which is readily installed and which will be durable and efficient in service.

These and other objects I attain by the construction shown in the accompanying drawing, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a fragmentary plan view of a violin equipped in accordance with my invention;

Figure 2 is a side elevation of the peg box, and associated structure;

Figure 3- is a longitudinal sectional view therethrough Figure 1 is a section on the line H of Figure 1.

Referring now more particularly to the drawing, the numeral 10 generally designates the neck, 11 the nut and 12 the peg box of a violin. These peg boxes, as is well known to those familiar with the art, have the side walls 13 thereof provided with apertures 14 for the reception of the tuning pegs of the instrument. In accordance with my invention, I provide a pair of plates 15 which are secured at opposite sides of the peg box to the walls 13 thereof by securing elements, designated at 16. These plates rotatably support opposite ends of pegs 17 which are eight in number and are arranged in substantially aligned superimposed pairs. sponding ends of two pairs of these pegs project through one of the plates 15 while the opposite ends of the remaining pegs project through the other plate 15. The projecting Correends of such pegs are each equipped with a worm gear 18 having coacting therewith a rotatable key operated worm 19 mounted in suitable bearings 20 carried by the associated plate. The worms of each pair of pegs which are carried by a given plate are preferably arranged in substantial alignment and are 'WGll separated from one another, so that there may be no confusion in handling the same. i

Of the pegs 17, those lying nearest the bottom of the peg box pass through the peg openings 14 of the walls 13 ofthe peg box, while the remaining pegs extend over the upper edges of these walls. These pairs of violin, the pegs of each pair mounting similar strings as E, A, D or G strings.

It will be obvious that the ordinary nut construction will necessarily be modified for the reception of the increased number of strings and that this will also be the case with the bridge 21 and tail piece 22. In modifying the tail piece 22 for the reception of the strings, the structure illustrated is preferably employed, the tail piece being provided with four openings 23 for the passage of the knotted or otherwise enlarged ends of the strings and each opening 23 having in its forward wall forwardly divergent slots 24: into which the strings above the knots may be inserted.

It will be obvious that with attachments of this character, the structure of the ordinary violin, viola, cello or the like may be readily modified to permit the use of an increased number of strings thereon without in any manner injuring the instrument. It will also be obvious that the construction herein illusings in its side walls, a pair of plates secured pegs which are four in number are each adapted to secure and ad ust a string for the to the outer faces of said side walls and mounting an increased number of pegs, certain of said pegs being directed through the openings of the peg box walls.

2. In combination with a violin having the usual peg box the side Walls of which are provided with peg receivingopenings adapted to receive a certain number of pegs, a pair of plates secured to the outer walls of the peg box, pairs of pegs having their ends mounted in the plates, said pairs'of'pegs corresponding in number to the number of the pegs that the peg box is adapted to receive, certain of said pegs extending through the peg receiving openings of the peg box, and means for rotatably adjusting said pegs.

3. In combination with a violin having the usual peg box the side walls of which are provided With. peg receiving openings adapted to receive .a certain number of pegs, a pair of plates secured to the outer walls of the peg box, pairs of pegs having their ends mounted in the plates, said pairs of pegs corresponding in number to the number of the pegs that the peg box is adapted to receive, certain of said pegs extending through the peg receiving openings of the peg box, each of said pairs of pegs having corresponding ends thereof projecting outwardly beyond the outer face of one of the plates and provided with a Worm gear, and aligned worms associated with the worm gears of the egs of each pair and mounted upon the outer aces of said plates.

In testimony whereof I hereunto aflix my signature.

GEORGE R. PETIT.
